新库，不知道谁装的
拿过来要我导数据并且割接
为了方便建了个权限很高的用户

create user an identified by an;
grant dba to an;

建完后试下看能不能删掉

SQL> drop user an;

ORA-01001: 无效的游标
ORA-00600: 内部错误代码，参数: [qmxiUnpPacked2], [121], [], [], [], [], [], []

Note:235423.1：

If your shared_pool_size and java_pool_size are less than 150Mb the do the
following ：

1/ Set your shared_pool_size and java_pool_size to 150Mb each. In some case
you may need to use larger pool sizes.

2/ Get the xdbpatch.sql script. from Note 237305.1

3/ Copy xdbpatch.sql to $ORACLE_HOME/rdbms/admin/xdbpatch.sql having taken a
backup of the original file first

4/ Restart the instance with:

startup migrate;

5/ spool catpatch

@?/rdbms/admin/catpatch.sql

--------------------------------------

于是照做

1、调整shared_pool_size到160000000
调整java_pool_size到160000000

重启实例，错误仍然存在

2、关闭实例
复制$ORACLE_HOME/rdbms/admin/xdbpatch.sql到其他路径做备份
关闭实例

startup migrate

@?/rdbms/admin/catpatch.sql
